Except that basically nobody cares about "being tracked across the whole internet", as shown by GA, Facebook, etc being on virtually every popular website and nobody noticing or caring at all. If you care enough to make even the most trivial change in behavior, then you're optimistically 1 in 1000.
I said that I care and that I hope that I am not a customer of businesses that track me and contribute to google's tracking. In that case I am 1 in 1000 and if a site doesn't work without GA and I don't have to use it (as in to file my taxes have to) then I won't I will purchase from a competitor.
EDIT
Most people do notice and do care this has come up in countless conversations. They just accept it as a necessary evil that they can't do anything about and accept (wrongly) that they as a individual can't change the world.
